Video Sync with Events

Hi!

I'm curious if anyone knows of a plugin that will allow me to trip events at certain times throughout the playtime of a video.

Example: at 30 seconds, I want to run a function. Then at 36 seconds, I want to run another function, etc. etc.

For obvious reasons, I can't just set a timeout and expect that the events will occur at the precise moment during the video.

Any ideas welcome!
Thanks
